How is MOQ split across colours and sizes?

Short answer: Underwear MOQs usually work at several levels at once. There is often a minimum per style, set by the cost of setting up cutting and sewing, and a minimum per colour, set by fabric dyeing, elastic and sometimes printed or jacquard waistbands. Sizes then divide each colour, and some factories also set a minimum per size so that cutting stays efficient. The colour minimum is often the hardest constraint: if fabric is dyed to order, the dye house has its own minimum lot, and a custom-colour waistband may have a minimum length that covers far more pieces than one small colour needs. Stock fabrics and stock elastics in standard colours usually allow smaller splits. Packaging adds another level, since printed boxes or bags can have their own minimums per design. Each colour and size combination also becomes a separate stock unit; GS1 guidance is that each size and colour variant needs its own GTIN, which matters for retail and marketplace listings. To plan, ask the factory for minimums at style, colour and size level, plus fabric, elastic and packaging minimums, and ask which colours are stock. Then choose fewer colours at proper depth, or use stock colours to widen the range, and agree how size quantities may be adjusted within each colour.

Levels of MOQ

• Per style.
• Per colour.
• Per size within each colour.
• Per packaging design.

What drives the colour minimum

• Fabric dye lot minimums.
• Custom elastic or waistband minimums.
• Thread and trim matching.

Ways to fit the MOQ

• Use stock fabric and elastic colours.
• Share one waistband across colours.
• Start with core colours.
• Use neutral packaging across colours.

A worked example

As an illustration, a brand could launch two core colours on custom fabric at full depth, add two stock-fabric colours at the lower stock minimum, and use a black waistband shared by all four.

Size splits

A factory may accept uneven size quantities within a colour as long as the colour total is met. Ask whether a small minimum per size applies, since very small runs of edge sizes can still be costly.

Reorders and colour minimums

The colour minimum usually applies again on reorders, especially for custom-dyed fabric. A colour that sells out may need to be reordered at the full colour minimum, so ask in advance whether fabric or elastic can be held in stock, or dyed from greige, to shorten the reorder.

Limits

Minimums differ by factory, mill and material. Confirm them in the quotation for each order rather than assuming they repeat.

Facts, recommendations and uncertainty

Established: MOQs often apply per style, colour and size, with colour driven by fabric and elastic minimums. Recommendation: ask for minimums at each level and plan colour depth first. Uncertain: which colours will sell best in a first launch.
